System Board Components
The following describes the main components of the system board:
• Dual PA-RISC processors:
— One or two processors enabled in the HP 9000 rp3410 server
— One, two, or four processors enabled in the HP 9000 rp3440 server
• ZX1 I/O and memory controller
• ZX1 PCI bus controller
• Processor dependent hardware controller
• Field processor gate array controller
• BMC
• SCSI controller
• IDE controller
• USB controller
• 10/100/1000 LAN
PA RISC Processor
The system board consists of two Zero Insertion Force (ZIF) processor sockets, the Core Electronic
Complex (CEC), and circuits for clock and power generation and distribution, boundary scan,
In-target Probe (ITP), and debug.
The Front Side Bus (FSB) is the IA64 processor bus based on bus protocol from Intel. This enables
processor customer self-repair (CSR) parts to be dropped in, provided that electrical and
